Method of managing the loading of a bucket (BU) of a work vehicle (WL) with bulk material accumulated on the ground to form a pile (BK), the method comprising a step (Step 6) of detecting a contact of the bucket with the pile when, during a condition of advancement of the vehicle according to a first speed value, an increase in a pressure value is detected in a hydraulic actuator supporting the bucket, exceeding a first predetermined pressure threshold (Pb + Gl), and at the same time a reduction or invariance in the advancement speed of the vehicle with respect to said first speed value, wherein said first predetermined pressure threshold is calculated as the sum of an average value (Pb) of the pressure value calculated in a time interval (T) during said advancement condition and a first guard factor (G1).

Agricultural or work vehicle comprising a processing unit (UCM), at least one hydraulic actuator (A1 - A3) served by a working part, a control lever (JK, RL) to control said at least one hydraulic actuator, a hydraulic pump (P), a hydraulic accumulator (HT), at least one open-centre directional valve (V1 - V3) operatively connected to control said at least one hydraulic actuator (A1 - A3) in function of an electrical signal generated by said control lever (JK, RL), a hydraulic oil collection tank (T), a diverter valve (V) arranged to alternatively connect a first hydraulic line for partialisation (PR) of the open-centre directional valve with said collection tank (T) and with said hydraulic accumulator (HT), when the following conditions are simultaneously verified: a) a pressure value measured at the hydraulic accumulator (HT) is lower than a first predetermined threshold (Th1) and b) said control lever (JK, RL) is in position of rest.

A controller (452) for a baler (410). The controller (452) is configured to receive a torque value (457), representative of the torque passing through a component of the baler (410), and compare the received torque value (457) with a torque setpoint. The controller (452) is then configured to determine a target speed (454) for the baler (410) based on the difference between the received torque value (457) and the torque setpoint.

Balancing system for engines comprising at least one three-cylinder bank comprising a first eccentric mass (MA) fixed in rotation with one end of a crankshaft (CS), a second eccentric mass (MB) rotatably associated with said end in a coaxial manner with the crankshaft, a primary gear wheel (M2) fixed or coinciding with a piston-counter-weight of the crankshaft and a transmission (T) arranged to transmit the motion from the primary gear wheel (M2) to the second eccentric mass (MB), so that the second eccentric mass is counter-rotating with respect to the primary gear wheel (M2).

An agricultural vehicle includes a baler that is either connected to or integrated with the agricultural vehicle. The baler has a pickup unit including a rotatable reel for introducing crop material into a baling chamber of the baler. A drive system rotates the reel. A feedrate control system is configured for calculating a value indicative of an amount of crop entering the baler at the pickup unit and adjusting a function of the vehicle based on the calculated value.

The present invention provides a crop cutting device (1) comprising a crop guiding surface (3), a plurality of knives (5) arranged side-by-side, wherein each knife (5) is pivotable about a knife axis (7) between a retracted inoperative position. The crop cutting device further comprises a plurality of operating units (11) in parallel to the plurality of knives (5). The crop cutting device comprises a selector mechanism (13) configured to selectively engage one or more of the plurality of operating units (11), wherein the selector mechanism (13) includes a rotatable shaft (17) comprising a plurality of engagement elements (19) configured to engage with the respective operating unit (11). The operating units (11) are movable between a disengaged position and an engaged position by a lifting mechanism (23) comprising an elongate element extending between a first side and a second side of a main frame (21).

In an agricultural implement, a pick-up assembly (1) is coupled to the frame (3) of the implement though at least one hydraulic actuator (15). The actuator comprises a cylinder (20), a first piston (23) and a rod (24) attached to the first piston. The cylinder (20) and the rod (24) are pivotably connected to the pick-up assembly (1) and to the frame (3) or vice versa, so that the actuator enables pivoting at least part of the pick-up assembly about a horizontal pivot axis (6), thereby lifting or lowering the assembly relative to a ground level (2). The cylinder (20) comprises an inlet port (27) positioned so that lifting the pick-up is enabled through the supply of hydraulic fluid to the inlet port. According to the invention, a second piston (25) is arranged in the cylinder, between the inlet port (27) and the first cylinder (23), and the rod (24) comprises an internal channel (24) that provides access to an interior space (33) of the cylinder, situated between the two pistons. This configuration enables setting a fixed stop position by supplying a given volume of hydraulic fluid between the pistons (23,25) or between the second piston (25) and the inlet port (27) of the cylinder, and maintaining said volume in the thus created space.

A gauge wheel system for an agricultural header includes a gauge wheel arm assembly configured to rotatably support a gauge wheel and pivotally couple to a header frame of the agricultural header. The gauge wheel system also includes a bell crank configured to pivotally couple to the header frame and a damper pivotally coupled to the gauge wheel arm assembly and the bell crank. The damper is configured to urge the gauge wheel arm assembly to pivot downwardly relative to the header frame while the gauge wheel arm assembly is in a ground-engaging position. The gauge wheel system also includes an actuator coupled to the bell crank and configured to couple to the header frame. The actuator is configured to drive the bell crank to rotate to move the gauge wheel arm assembly between a ground-engaging position and a storage position.
